Abstract
A method of manufacturing a multi-domain liquid crystal display device having a pixel includes the steps of forming an alignment film on at least one of a first and second substrate; covering the alignment film with a mask, there being included a first surface having a plurality of light-transmitting portion and light-shielding portions and a second surface having light-shielding portions corresponding to the light-transmitting portions; radiating light from an upper portion of the mask; and assembling the first and second substrates.

A method for manufacturing a multi-domain liquid crystal display device having a pixel comprising:
- providing a substrate;
- forming an alignment film on the substrate;
- arranging a plurality of first light-transmitting portions and first light-shielding portions at a first distance over the alignment film on the substrate, wherein the first light-transmitting portions and first light-shielding portions alternate with one another;
- arranging a plurality of second light-transmitting portions and second light-shielding portions at a second distance over the alignment film on the substrate, wherein the second light-transmitting portions and the second light-shielding portions alternate with one another at constant intervals;
- wherein the first light-shielding portions correspond to the second light-transmitting portions and the first light-transmitting portions correspond to the second light-shielding portions;
- and
- irradiating light onto the alignment film through the first and second light-transmitting portions.
A method for manufacturing a multi-domain liquid crystal cell comprising:
- providing a substrate on which an alignment film is formed;

- and
- irradiating the light-transmitting portions using the mask.
A method for manufacturing a multi-domain liquid crystal cell comprising:
- providing a substrate;
- covering a first area of the substrate on which an alignment film is formed with a mask;
- arranging a plurality of first and second light-transmitting and light-shielding portions at constant intervals on a first surface of the mask;
- arranging a plurality of first and second light-transmitting and light-shielding portions at constant intervals on a second surface of the mask, wherein the light-shielding portion is arranged in a position corresponding to the light-transmitting portion of the first surface and the light-transmitting portion is arranged in a position corresponding to the light-shielding portion of the first surface;
- covering a second area of the substrate with an opaque mask;
- and
- irradiating light on the substrate at an angle including the first area and the second area.
